Abstract

The presence of mammalian lignans, mainly enterolactone, in human plasma has been related to lower incidence of certain cancers and cardiovascular disease. The plant lignans secoisolariciresinol and matairesinol have been reported to be precursors of mammalian lignans, but recently other plant lignans relatively abundant in the diet have also been identified as precursors. To evaluate the importance and contribution of these new dietary precursors to the mammalian lignan formation in vivo, metabolic studies in human subjects must be carried out. For this purpose a method based on high-performance liquid chromatography using coulometric electrode array detection for the simultaneous determination of nine plant lignans and two mammalian lignans in human plasma was developed, validated, and shown to fulfill the reliability criteria.
